Abstract

DIFERENCIAL AUTOBLOQUEANTE QUE CONSTA DE UN ORGANO DE ENTRADA (3A;3B;103A;104B), DOS ORGANOS DE SALIDA (8A,9A;8B,9B;105A,104A,125;105B,103B), DOS ARBOLES DE SALIDA ASOCIADOS, CADA UNO DE ELLOS, A UNO DE LOS ORGANOS DE SALIDA, Y UNOS ELEMENTOS DE SOLIDARIZACION (22,23;29,30,38,39;127,128;144,145) MOVILES AXIALMENTE PARA SOLIDARIZAR, POR SU DESPLAZAMIENTO AXIAL, DOS DE LOS TRES ORGANOS DE ENTRADA Y DE SALIDA. CONSTA DE ELEMENTOS DE BLOQUEO (14,16;33,35,37;120A,122A;120B,122B) PARA OPONERSE A DICHO DESPLAZAMIENTO AXIAL DE LOS ELEMENTOS DE SOLIDARIZACION MIENTRAS QUE EL PAR DE RESISTENCIA EN DICHO ARBOL DE SALIDA CONSERVA UN VALOR SUFICIENTE.SELF-LOCKING DIFFERENTIAL CONSISTING OF AN ENTRANCE ORGAN (3A; 3B; 103A; 104B), TWO EXIT ORGANS (8A, 9A; 8B, 9B; 105A, 104A, 125; 105B, 103B), TWO ASSOCIATED EXIT TREES, EACH ONE OF THEM, ONE OF THE DEPARTURE BODIES, AND SOME ELEMENTS OF SOLIDARIZATION (22,23; 29,30,38,39; 127,128; 144,145) MOBILE AXIALLY TO SOLIDARIZE, BY ITS AXIAL DISPLACEMENT, TWO OF THE THREE ORGANS OF ENTRY AND EXIT. IT CONSISTS OF LOCKING ELEMENTS (14,16; 33,35,37; 120A, 122A; 120B, 122B) TO OBJECT TO SUCH AXIAL DISPLACEMENT OF THE SOLIDARIZATION ELEMENTS WHILE THE PAIR OF RESISTANCE IN SUCH OUTPUT TREE RETAINS A SUFFICIENT VALUE .
